使用float.is_integer()方法检查浮点数是否为整数,例如result = (3.00).is_integer()。 如果浮点数是有限的整数,float.is_integer()方法将返回True,否则返回False。 importmath# ✅ check if float is whole number using float.is_integer()result_1 = (3.00).is_integer()print(result_1)# 👉️ Tru...
Number 数字:int float 数值运算 String 字符串 Boolean 布尔值 List 列表 Tuple 元组 Dictionary 字典 Sets 集合 一、数据类型的查询 当面对未知数据类型的数据时,我们脑子里应该有这么一个问题:我们怎样才能查到未知数据的数据类型呢? 这里就让我来简单的回答下你的困惑,在Python中我们可以通过两种内置函数来查询对...

>>>thing="Hello">>>type(thing)<class'str'>>>thing=28.1>>>type(thing)<class'float'> type()方法返回对象的类型。这些示例证实了变量的类型可以被允许更改,并且 Python 在更改时正确地推断了该类型。 静态类型(Static Typing) 动态类型化的反面是静态类型化。 在不运行程序的情况下执行静态类型检查。 在...

值不是数据类型，数据类型不是值 如果value等于10.2 那么 value is 10.2 等于True,value is not 10.2 等于False
Another method to check if a variable is a number is using a try-except block. In the try block, we cast the given variable to an int or float. Successful execution of the try block means that a variable is a number i.e. either int or float: myVariable = 1 try: tmp = int(my...
